  • an actuator device for a hydraulic actuation system of a brake/clutch of a motorcycle in accordance with claim 1.
  • an actuator device for a hydraulic actuation system of a brake/clutch of a motorcycle comprising:

  • the pusher is inserted inside the bushing according to a screw-nut coupling with respect to an adjustment axis X-X placed parallel and eccentric with respect to the symmetry axis, according to said eccentricity.
  • the tang of the pusher is offset by said eccentricity with respect to the symmetry axis Y-Y.
  • tang is integrally connected to a knob for roto-translating it with respect to the bushing along the adjustment axis.
  • a spring is interposed between the pusher and the lever, having at least one end fixed to the lever to adjust the rotation of the pusher in steps.

  • said spring and/or said knob are configured so as to provide at least one limit stop of the rotation of the pusher, so as to achieve a limit stop abutment between the spring and knob upon reaching a predetermined position of the adjustment of the pitch.
  • said spring and/or said knob are configured so as to provide two limit stops of the rotation of the pusher, in mutually opposite directions, so as to achieve a limit stop abutment between the spring and knob to reach two respective predefined maximum and minimum pitch positions.
  • said spring comprises a folded portion about an outer collar integral with the bushing, said folded portion obtaining at least one limit stop abutment against a corresponding shoulder formed on the knob.
  • the knob comprises an inner gripping portion which can rotate without interfering with said folded portion of the spring and at least one shoulder which protrudes from said inner gripping portion so as to interfere with the folded portion of the spring when reaching a limit stop.

  • vehicles are both cars and motorcycles.
  • the actuator device 4 may be of any type and size, preferably adapted to be mounted on a handlebar of a motorcycle and to operate a hydraulically-operated brake and a clutch.
  • the actuator device 4 for a hydraulic actuation system of a brake/clutch of a motorcycle comprises a support structure 8 associable with a handlebar 12 of a motorcycle.
  • the type, size and materials of the support structure which must be considered in the most general sense possible, are irrelevant.
  • the actuator device 4 further comprises an actuation assembly 16 having a push rod 20, operatively connectable to at least one braking device (not shown), and an actuation lever 24 connected to the support structure 8.
  • the push rod 20, in a known manner, comprises a thrust end 26 adapted to be pressed by the actuation lever 24 of the actuator device 4 and an inner end 28 operatively connectable to at least one braking device.
  • the connection of the inner end 28 to at least one braking device can be of any type and is preferably a hydraulic connection but can also be mechanical.
  • the actuator device 4 comprises actuation lever 24 which is rotationally connected to the support structure 8 about an actuation axis S-S in a first and a second rotation direction, respectively towards and away from the associable handlebar.
  • the rotational connection of the actuation lever 24 to the support structure 8 firstly allows to apply a thrusting action against the push rod 20 to operate the brake or clutch.
  • the actuation lever 24 is rotational towards and away from the handlebar 12, in order to allow the adjustment of the distance of the actuation lever 24 from the handlebar 12 itself: such an adjustment can be used by the user to adjust the rest position of the lever itself as a function of the principles of ergonomics or in any case to his or her preferences.
  • the actuation lever 24 is provided with a pusher 32 adapted to interface with said push rod 20.
  • the pusher 32 is housed/supported within an appropriate appendix 36 obtained on the actuation lever 24.
  • the actuator device is provided, in a known manner, with thrust means 37 which elastically bias the actuation lever 24 towards the handlebar 12 so as to promote the contact between the pusher 32 and the thrust end 26 of the push rod 20.
  • the actuator device 4 further comprises adjustment means 40 adapted to modify both the angular position, in a rest condition, of the pusher 32 and of the actuation lever 24 with respect to the handlebar and to modify a pitch 44 between the actuation axis S-S of the actuation lever 24 and a contact and thrust point P of the pusher 32 on said push rod 20.
  • the adjustment means 40 comprise a bushing 48 inserted in a counter-shaped cylindrical seat 52 of the actuation lever 24 having a symmetry axis Y-Y, so as to be able to at least rotate about said symmetry axis Y-Y.
  • the adjustment means 40 further comprise said pusher 32 having a tang 56, inserted inside the bushing 48, and a bowl 60, integral with the tang 56, which interfaces with the push rod 20.
  • the bowl 60 comprises a concave portion with a spherical cap shaped profile so as to be able to interface with the thrust end 26 of push rod 20, even modifying the relative inclination between pusher 32 and push rod 20.
  • said bowl 60 is offset with respect to the symmetry axis Y-Y by an eccentricity E, so as to be able to vary the pitch 44 by turning the bowl 60 about the symmetry axis Y-Y.
  • the pusher 32 slides with respect to the actuation lever 24 parallel to said symmetry axis Y-Y.
  • the translation and eccentric rotation movements of the pusher 32 with respect to the symmetry axis Y-Y are mechanically independent of each other.
  • This option allows the user to achieve a high level of customization of the actuation lever 24, both in terms of actuation sensitivity and in terms of distance from the handlebar 12.
  • the bushing 48 is fitted in the cylindrical seat 52 so as to be able to rotate and not translate with respect to the seat along the symmetry axis Y-Y.
  • the pusher 32 is inserted inside the bushing 48 according to a screw-nut coupling 72 with respect to an adjustment axis X-X placed parallel and eccentric with respect to the symmetry axis Y-Y, according to said eccentricity E.
  • the tang 56 of the pusher 32 is misaligned by said eccentricity E with respect to the symmetry axis Y-Y.
  • the bushing 48 comprises an outer collar 76 to rotate it, so as to rotate the pusher eccentrically with respect to the symmetry axis Y-Y.
  • the pitch 44 can thus be adjusted in a totally separate manner, i.e. without modifying the rest position of the actuation lever 24 in any manner.
  • said outer collar 76 is provided with knurls or a section having symmetry which is not a rotation solid in order to facilitate the grip and manual rotation by a user.
  • said outer collar 76 is arranged between appendix 36 and bowl 60.
  • the tang 56 is integrally connected to a knob 80 for roto-translating it with respect to the bushing 48 along the adjustment axis X-X.
  • connection between the tang 56 and the knob 80 can occur by means of a shape coupling, e.g. with a non-cylindrical peg which engages a corresponding complementarily shaped seat.
  • Both the outer collar 76 and the knob 80 can be provided with signs and graphic references regarding the type of adjustment that can allow. Obviously, it is also possible to provide corresponding graphic indications, references, alignments charts and the like at the appendix 36 of the actuation lever 24.
  • the roto-translation is due to the screw-nut screw coupling 76 between push rod 20 and bushing 48.
  • it is the overall translation of the push rod 20 with respect to the bushing 48 that counts because the rest position of the actuation lever 24 and its distance from the handlebars are changed by virtue of it.
  • a spring 84 is interposed between the pusher 32 and the actuation lever 24, having at least one locking end 88 fixed to the actuation lever 24 to adjust the rotation of the pusher 32 in steps.
  • Said spring 84 also implements a step-lock for the rotation of the bushing 48, by means of at least one tooth 92 which engages between the knob 80 and a portion of a body or plate 96 of the spring 84.
  • the spring 84 itself does not rotate and acts as a fixed reference for both adjustments, i.e. for the adjustment of the pitch 44 and for the adjustment of the rest position of the actuation lever 24.
  • said spring 84 and/or said knob 80 are configured so as to provide at least one limit stop of the rotation of the pusher 32, so as to achieve a limit stop abutment between the spring 84 and knob 80 upon reaching a predetermined position of the adjustment of the pitch 44.
  • the predetermined position is in an end of adjustment position, i.e. in a maximum or minimum distance position 44.
  • said spring 84 and/or said knob 80 are configured so as to provide two limit stops of the rotation of the pusher 32, in mutually opposite directions, so as to achieve a limit stop abutment between the spring 84 and knob 80 to reach two respective predefined maximum and minimum pitch 44 positions.
  • the spring 84 comprises a folded portion 108 about the outer collar 76 rigidly coupled to the bushing 48; the folded portion 108 performs at least one limit stop abutment against a corresponding shoulder 112 formed on the knob 80.
  • the knob 80 comprises an inner gripping portion 116 which can rotate without interfering with said folded portion 108 of the spring 84 and at least one shoulder 112 which protrudes from said inner gripping portion 116 so as to interfere with the folded portion 108 of the spring 84 when reaching a limit stop.
  • This embodiment adds a function of locking of the center-to-center adjustment in the lowest and highest position.
  • a function improves the legibility of the change of pitch 44, whereby univocally defining the limits: therefore, the passage is from a continuous type adjustment which goes from maximum to minimum and back from minimum to maximum as one continues to turn, to an adjustment which ensures the achievement of the extremes of adjustment at the opposite limit ends.
  • This function is achieved by obtaining a rotation block through the shoulder 112 or protrusion on the knob 80 which allows the adjustment of the pitch 44: in limit position, the shoulder 112 interferes with the spring 84, i.e. with the folded portion 108, not allowing the further rotation.
  • the spring 84 already employed to provide the snap lock for adjustment of the pitch 44 and distance lever, also assumes the function of a stop of the adjustment of the pitch 44 in the limit positions. Therefore, the adjustment of the pitch 44, by virtue of the presence of the limit stop, is easier and more intuitive.
  • the bushing 48 comprises an outer threaded surface 100 which meshes with an adjustment screw 104, associated with the actuation lever 24, to allow the rotation the bushing 48.
  • the meshing between the outer threaded surface 100 of the bushing 48 and the adjustment screw 104 is of the irreversible type.
  • the adjusting screw 104 may be operated from outside the actuation lever 24 by inserting a screwdriver, a hex key or the like, which is inserted in a hole on the actuation lever 24, which allows access to a head of said adjustment screw 104.
  • a spring 84 is interposed between the pusher 32 and the lever 24 or bushing 48, having at least one locking end 88 fixed to the lever 24 or bushing 48 to adjust the rotation of the pusher 32 in steps and thus to adjust the pitch 44.
  • the spring 84 itself is provided with a tooth 92 which mates with the knob 80.
  • the spring 84 does not rotate and acts as a fixed reference for adjusting the pitch 44.
  • the bushing 48 is inserted in the cylindrical seat 52 by means of a screw-nut type coupling centered according to the symmetry axis Y-Y so as to roto-translate parallel to said symmetry axis Y-Y.
  • the pusher 32 and the bushing 48 are rotatably free and axially bound to each other with respect to said symmetry axis (Y-Y).
  • the tang 56 of the pusher 32 is coaxial with said symmetry axis Y-Y and the bowl 60 has a centerline axis M-M off-center with respect to the symmetry axis Y-Y by said eccentricity E.
  • Said centerline M-M and the symmetry axis Y-Y are mutually parallel and spaced apart.
  • the tang 56 and the bowl 60 are not mutually aligned and by rotating the tang about the symmetry axis Y-Y, by virtue of the knob 80, one obtains the variation of the pitch 44.
  • figures 15-16 show two opposite adjustments of the pitch, respectively a 'rigid' adjustment ( figure 15 ) and a soft setting ( figure 16 ). As can be seen to vary such an adjustment does not change the rest position of the actuation lever 24.
  • Figures 17-18 represent two opposite adjustments of the rest position of the actuation lever 24, respectively an adjustment of minimum distance from the handlebar 12 ( Figure 17 ) and an adjustment of maximum distance from the handlebar 12 ( Figure 18 ). As can be seen, varying such an adjustment does not change the pitch 44.
  • the tang 56 is integrally connected to a knob 80 for roto-translating it with respect to the bushing 48 along the adjustment axis.
  • the bushing 48 is, in turn, provided with an outer collar 76 for manual rotation thereof by a user.
  • a spring 84 is interposed between the pusher 32 and the actuation lever 24, having at least one locking end 88 fixed to the actuation lever 24 to adjust the rotation of the pusher 32 in steps.
  • said spring 84 also implements a step-lock for the rotation of the bushing 48, by means of at least one tooth 92 which engages between the knob 80 and a portion of a body or plate 96 of the spring 84.
  • the spring 84 does not rotate and acts as a fixed reference for both adjustments, i.e. for the adjustment of the pitch 44 and for the adjustment of the rest position of the actuation lever 24.
  • both the outer collar 76 and the knob 80 are arranged on the same side with respect to the pusher 32, e.g. on the opposite side of the bowl 60.
  • the outer collar 76 and the knob 80 are close to each other and can be easily operated by the user, also during a race.
  • the present invention allows to overcome the drawbacks raised in the prior art.
  • the present invention provides a device which is simple, robust, intuitive to use and innovative; said device allows to adapt the driver's adjustment in an intuitive and fast manner, without renouncing the possibility to perform the adjustment of the rest position of the lever and the pitch of the lever itself in a separate manner.
  • the device can be applied to pre-existing solutions as a 'retrofit'.
  • the coaxial adjustment allows the adjustment of the pitch and the distance close each other and easily identifiable, but also, at the same time, separate.
  • the adjustment of the pitch is intuitive in use (Hard-Soft) and preferably has 8 total positions.
  • the system is easy to install in line, even on existing products, without needing to make changes to the products themselves or to the lines.
  • the system is versatile and can be applied to all levers which do not provide direct operation of the microswitch (PR, PS, Offroad, etc.).
